“…The methodology [ 31 ], presented in Figure 2 , was used in simulation testing to assess the stability of the mobile crane handling system. The simulation model built with the use of the integrated CAD/CAE system makes it possible to assess the stability of the crane system on the example of the HIAB XS 111 crane with the proposed interaction and control system [ 2 , 3 ].…”

In this work, the authors analyse the influence of the order and range of sequential movements of a crane’s working members on the accuracy of the final cargo positioning. The analysis was conducted on the basis of a specially developed method in which the authors proposed the introduction of a geometrical indicator of positioning the load in the intermediate positions (after completing each movement sequence) and in the target position, depending on the adopted control strategy and the accuracy of kinematic input of the working mechanisms (powered mechanisms). A mathematical model was presented to enable the accuracy of unidirectional positioning of the crane’s working members when conducting sequential movements controlled through the rotation of the crane column, inner and outer boom, and retractable stages of the six-section telescopic boom. Sample results of the numerical simulations showing the influence of the assumed kinematic inputs of the crane members on the accuracy of unidirectional angular and linear positioning and, consequently, on the accuracy of the final positioning of the transported cargo, were presented. Moreover, an indicator of the cargo positioning accuracy dependent on the location of an operator or a video camera and the trajectory of the cargo was developed, allowing the formulation of application conclusions.

“…3 shows the importance of considering the role of geometric dimensions in achieving dynamic balance during operation as a necessity for safety [32,34]. Many scientific kinds of research have been concerned with studying the design, construction, and dynamic control of cranes operation in construction projects [35]- [38]. Most of the research has focused on the study of the dynamic to insuring and achieving safe operation [37]- [39].…”

Mechanical engineers have adapted 3D coordinate technology in the design and implementation of cranes to accelerate the production of construction industries, especially tall structures such as buildings and bridges. Structural engineering projects such as buildings, infrastructure, and bridges are central to the development of human civilization. However, it is also a source of some types of accidents and even disasters, which will be referred to in this paper as structural engineering disasters. This paper discusses the concept, types, and characteristics of structural engineering disasters, especially those that talk about the use of high-level 3D coordinate equipment (tower or mobile cranes) and ways to mitigate them. The accidents in practice occur due to dynamic balance defects during equipment operation, which is usually due to incorrect selection or behavior on the construction site, installation, maintenance, operation, or ambient environmental conditions. Structural engineering disasters occur frequently and globally because they are closely related to human behavior and performance. This paper confirms that solutions can be found entrepreneurial to manage the situation to reach the appropriate operation to mitigate the accidents, through implementing the proposed administrative and engineering recommendations related to an accurate scientific method to meet these challenges. The engineering recommendations are based on ensuring the proper implementation of maintenance, operation, and calibration under the engineering standards. While the administrative recommendations focus on ensuring the follow-up of the safety procedures for implementing maintenance programs and the appropriate behavior of operator and scientifically signal person to meet these challenges.

“…These forces of various origins could cause a loss of stability or a decrease in accuracy at the end-point. The former was studied both in terms of structural [8,9] and dynamic stability [10,11]. The other research on dynamic properties of loader cranes concerned tip over stability of mobile boom cranes [12].…”

Paper presents a method of simplifications used over numerical studies on dynamic properties of a hydraulic loader crane. Simplification concerns hydraulic actuators and allows for a significant reduction in the time of building model and calculations. Modal analysis of a loader crane using the finite element method, for both complex and simplified models, was carried out. The modal analysis computation times for both models were compared. Next, the results obtained on the basis of simplified model were compared with the results of experimental studies.
